h.create(0) freezes

[pers972]

Try this code

`from harvesters.core import Harvester, ImageAcquirer

h = Harvester() h.add_file(r"C:\Users\SGL\Desktop\MATRIX VISION\mvIMPACT Acquire\bin\x64\mvGenTLProducer.cti") h.update() print(len(h.device_info_list)) print(h.device_info_list[0])

print(h.create(0)) `

And get this output C:\Users\SGL\PycharmProjects\pythonProject.venv\Scripts\python.exe C:\Users\SGL\PycharmProjects\pythonProject\ff.py 1 {'access_status': 1, 'displayname': 'Specim FX10e(70:f8:e7:b0:09:d0)', 'id': 'FX10e(70:f8:e7:b0:09:d0)', 'model': 'FX10e', 'parent': <genicam.gentl.Interface; proxy of <Swig Object of type 'std::shared_ptr< GenTLCpp::TLInterface > *' at 0x0000020C922E8D20> >, 'serial_number': '077000057871', 'thisown': True, 'tl_type': 'GEV', 'user_defined_name': ' ', 'vendor': 'Specim', 'version': 'Version 1.3'}

I'm trying different combination of versions Matrix Vision and Python. And program freezes. Why Imagerequirer don't creating? Thanks for all recommendation.

We also started to observe a similar behavior. Along with corrupted buffers as in #452

@kazunarikudo it seems that something might be broken in either latest mvGenTLproducer or genicam

Hi @pers972

Which version of Python, Harvesters, GenICam package and mvGenTLProducer.cti do you use?

As well which kind of Windows are you using?

Maybe you can also enable additional log information in Harvester (here is a Python code snipped to do so..):

import logging
import warnings
warnings.simplefilter('always') 

FORMAT = '%(name)s - %(levelname)s %(asctime)s: %(message)s'
logging.basicConfig(level=logging.DEBUG, format=FORMAT)

h = Harvester(logger=logging.getLogger("harvesters"))

Just to be said: I'm sorry but I wasn't able to reproduce the issue with mvGenTLProducer version 3.2, Harvesters 1.4.3 and genicam 1.4.0.

@sunavlis I will add some logging, indeed. We see this camera freeze mostly when we restart the streaming. The first connection usually works okay (but not always).

The issue is not reproducible in 100% of the cases, which makes it difficult to debug. We are using mvGenTLProducer version 2.50.1, harvesters==1.4.3, genicam==1.4.0

To circumvent the corrupted buffers issue, we set a high number of buffers (it seems to increase the probability to hang the camera)

P. S. If you are using the version 3.x of mvGenTLProducer without buying it, it does not really stream the video...

I'm using windows 11, what about versions python i'm trying different 3.7,3.8,3.9,3.11; Versions of MAtrix Vision 2.50.0, 2.50.1, 2.46.2, 2.3.4, harvesters 1.3.6 or last version. At my other PC working 1.3.6 harvesters and MATRIX VISION 2.3.4 with python 3.7, but when i'm installed on other PC this combination not worked
